Description

Technical Field

[0001] This utility model relates to the field of self-balancing scooter technology, specifically to a unicycle self-balancing scooter with an adjustable handlebar tension structure. Background Technology

[0002] A self-balancing scooter is an electric personal transportation device that automatically maintains its balance using built-in gyroscopes and sensors. Current self-balancing scooters include two-wheeled and one-wheeled models. Two-wheeled scooters have two wheels and pedals, offering high stability and are suitable for beginners and short commutes. One-wheeled scooters are for more advanced enthusiasts, requiring a higher level of balance and are often used for stunt performances or urban navigation.

[0003] With the continuous development of self-balancing scooters, to improve portability, a transport handle is usually installed. To save space, a flip-up transport handle structure is used, with one end hinged to the main body of the scooter. When not in use, the handle is flipped for storage, and when needed, it is flipped back for use. However, with prolonged use, the plastic material of the transport handle is prone to loosening or deformation at the hinge, resulting in an unstable connection between the handle and the scooter. To solve this instability, the current solution is to send the scooter back to the factory for repair or replace the handle, which is a cumbersome process that affects the user experience and fails to meet user needs.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figure 1-7As shown, this utility model discloses a unicycle with an adjustable handlebar tension structure, comprising a unicycle body 1 and a carrying handle 2. The unicycle body 1 is provided with a hinge seat 11. The carrying handle 2 includes a handle ring 21 and a connecting shaft 22. The hinge seat 11 is provided with a hinge hole 110 that mates with the connecting shaft 22. The handle ring 21 has an adjustment end and a connection end at its two ends, respectively. The connection end has a connection channel 212 that mates with the connecting shaft 22, and the adjustment end has an adjustment channel 211 that mates with the connecting shaft 22. The connecting shaft 22 has an adjustment head 221 and a connection tail 222 at its front and rear ends, respectively. The adjustment channel 211 has a front guide portion that mates with the adjustment head 221. The adjustment head 221 and the connection tail 222... 22 is respectively set in the adjustment channel 211 and the connection channel 212. The outer periphery of the adjustment head 221 and the connection tail 222 is provided with a tight-fitting inclined surface 223. The tight-fitting inclined surface 223 of the adjustment head 221 can cooperate with the inner wall of the adjustment channel 211 to achieve a tight fit between the adjustment head 221, the adjustment end and the hinge seat 11. The tight-fitting inclined surface 223 of the connection tail 222 can cooperate with the inner wall of the connection channel 212 to achieve a tight fit between the connection tail 222, the connection end and the hinge seat 11. The adjustment head 221 is threaded with an adjusting screw 23. The connection channel 212 is provided with an adjusting boss 213 that cooperates with the adjusting screw 23. The adjusting screw 23 can cooperate with the adjusting boss 213 to make the connecting shaft 22 move in the direction of the adjustment channel 211.

[0028] By adjusting the tight-fitting inclined surface 223 on the adjusting head 221 and the connecting tail 222, when the connection between the transport handle 2 and the hinge seat 11 becomes loose, the user adjusts the tightening screw 23, causing the connecting shaft 22 to move towards the adjusting channel 211. The tight-fitting inclined surface 223 gradually fits tightly against the inner wall of the adjusting channel 211 and the connecting channel 212. At the same time, the connecting end and the adjusting end gradually come into contact with the hinge seat 11. This quick adjustment of the handle's tightness effectively improves the flexibility of the transport handle 2 and meets the user's needs.

[0029] When tightening is required, a tool is inserted into the adjustment channel 211 to rotate the tightening screw 23 clockwise. Under the action of the tightening boss 213, the position of the tightening screw 23 in the adjustment channel 211 remains unchanged. The connecting shaft 22 gradually approaches the screw head of the tightening screw 23 to achieve tightening.

[0030] The cross-sectional shape of the adjustment head 221 is polygonal, and the front guide part is an adjustment contour surface that is disposed in the adjustment channel 211 and matches the shape of the adjustment head 221.

[0031] By setting the front guide, the relative rotation between the connecting shaft 22 and the handle ring 21 can be avoided, which would affect the user experience.

[0032] The connecting channel 212 is provided with a rear guide part that mates with the connecting tail 222. The cross-sectional shape of the connecting tail 222 is polygonal, and the rear guide part is a connecting contour surface provided in the connecting channel 212 that mates with the shape of the connecting tail 222.

[0033] By setting the rear guide portion, the connection stability between the connecting shaft 22 and the handle ring 21 can be further improved, and the relative rotation of the connecting shaft 22 relative to the handle ring 21 can be avoided.

[0034] An angle fixing sleeve 24 is fitted on the connecting shaft 22, and a hinged elastic buckle 3 is provided on the main body 1 of the balance vehicle. The hinged elastic buckle 3 can cooperate with the angle fixing sleeve 24 to fix the angle of the transport handle 2.

[0035] The hinge seat 11 is provided with a clearance mounting position that cooperates with the angle fixing sleeve 24. Hinges 111 are provided on both sides of the clearance mounting position, and hinge holes 110 are respectively provided on the two hinge arms 111.

[0036] The hinge arms 111 on both sides can effectively position the angle fixing sleeve 24, and the two hinge arms 111 can effectively improve the stability of the handle ring 21 connection.

[0037] The carry-on handle 2 also includes a reset torsion spring 25, which is sleeved on the connecting shaft 22. The reset torsion spring 25 is provided with an elastic foot, and the hinge seat 11 is provided with a reset mounting groove that cooperates with the elastic foot. The elastic foot is located in the reset mounting groove.

[0038] By setting the reset torsion spring 25, the handle ring 21 can be automatically retracted and reset without external force, thus improving the user experience.

[0039] The angle fixing sleeve 24 is provided with a rotating positioning block 241, the hinged elastic buckle 3 is provided with a rotating positioning groove 31 that cooperates with the rotating positioning block 241, and one end of the hinged elastic buckle 3 is provided with a pressing block 32.

[0040] The hinged elastic buckle 3 can be quickly adjusted by the user pressing the pressing block 32 to move the rotating positioning groove 31 away from the rotating positioning block 241.

[0041] An anti-rotation element 242 is provided on the angle fixing sleeve 24, and an anti-rotation groove 224 is provided on the connecting shaft 22. One end of the anti-rotation element 242 is placed in the anti-rotation groove 224. Through the cooperation of the anti-rotation element 242 and the anti-rotation groove 224, the angle fixing sleeve 24 can be driven to rotate synchronously when the carrying handle 2 rotates, so as to prevent the angle fixing sleeve 24 and the connecting shaft 22 from rotating relative to each other. When the adjusting screw 23 is tightened, when the connecting shaft 22 moves toward the adjusting channel 211, the anti-rotation element 242 does not affect the linear movement of the connecting shaft 22. The anti-rotation element 242 moves linearly relative to the connecting shaft 22 in the anti-rotation groove 224.

[0042] There are two rotating positioning blocks 241 and two rotating positioning slots 31. By setting two rotating positioning blocks 241, the angle positioning of the luggage handle 2 in the storage state and the use state can be respectively improved, effectively enhancing the user experience.

[0043] An elastic bushing 112 is provided in the hinge hole 110 and is sleeved on the connecting shaft 22. The elastic bushing 112 can prevent wear between the connecting shaft 22 and the hinge seat 11.

[0044] As can be seen from the above, the beneficial effects of this utility model are: by adopting its structure, it can effectively solve the problem that in the prior art, the transport handle 2 on the balance scooter is prone to loosening or deformation at the hinge with long-term use, resulting in an unstable connection between the handle and the balance scooter, and the problems of high subsequent maintenance costs and low efficiency. By adjusting the tight fitting inclined surface 223 on the adjusting head 221 and the connecting tail 222, when the connection between the transport handle 2 and the hinge seat 11 becomes loose, the user adjusts the tightening screw 23, so that the connecting shaft 22 moves towards the adjusting channel 211, and the tight fitting inclined surface 223 gradually fits tightly with the inner wall of the adjusting channel 211 and the connecting channel 212. At the same time, the connecting end and the adjusting end gradually fit with the hinge seat 11, which quickly adjusts the tightness of the handle, effectively improves the flexibility of the transport handle 2, and meets the user's needs.

[0045] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
